Well I just got my Inspire the other day from B&H. Battery worked, no issues, but Im pretty sure I have a bad USB port. I have used the search and read everything I can find on both this forum and the DJI forum. I think I'm going to have to send at least the controler back to B&H for a replacement. I updated the firmware on the AC but I was unable to connect the RC to the GO app, it just sits on how to connect. I tried to update with multiple USB formatted drives and the Micro USB card. The RC is green, the AC blinking Yellow. I tried Firmware 9.01.30 and 8.01.00, both loaded onto the AC, but nothing would load on the RC. Using an android/Note5 with debugging and MTP. I can control the gimbal and was even able take video. Any last tips before I contact B&H?
